The following description ofvarious examples is merely illustrative in nature and is in no wayintended to limit the disclosure, its application, or uses.Additionally, the advantages provided by the examples and embodimentsdescribed below are illustrative in nature and not all examples andembodiments provide the same advantages or the same degree ofadvantages.

Overview

In general, a bicycle carrier for transporting a bicycle on a vehiclerooftop may include two accessories, a fork mount and a tail mount. Thefork mount may be configured to attach a front fork of the bicycle to afirst crossbar on the vehicle rooftop, after removing a front wheel fromthe bicycle. The tail mount may be configured to secure a rear wheel ofthe bicycle to a second crossbar on top of the vehicle.

The fork mount may include a connector assembly configured to secure thefront fork to the fork mount. The connector assembly may include a pairof selectable inserts and an interchangeable skewer with a cam lever.The skewer may protrude through the selectable inserts, the front forkand the fork mount, to clamp the front fork against a clamping surfaceof the selectable inserts when the cam lever is in a closed position. Insome examples a through-axle of the bicycle front fork may be used inplace of the skewer. When a through-axle is interchanged for the skewer,the axle may similarly protrude through the selectable inserts, thefront fork and the fork mount, to clamp the front fork against aclamping surface of the selectable inserts when the axle is secured.

The tail mount may include a wheel clamp assembly configured to securethe rear wheel to the tail mount. The wheel clamp assembly may include awheel tray and a strap coupled to the wheel tray, which may extendthrough the rear wheel to hold the wheel against the wheel tray. Thewheel tray may be configured to be disposed at a plurality of angles asmeasured around a long axis of the second crossbar.

The bicycle carrier may include security features on either or both ofthe fork mount and the tail mount, and coverings may be included oversome areas for further protection. The fork mount and the tail mount maybe separate structures, or may be mounted on and/or part of a singlebicycle carrier. For example, the fork mount and/or the tail mount maybe part of a tray rack.

Examples, Components, and Alternatives

The following sections describe selected aspects of exemplary bicyclecarriers as well as related systems. The examples in these sections areintended for illustration and should not be interpreted as limiting theentire scope of the present disclosure. Each section may include one ormore distinct embodiments or examples, and/or contextual or relatedinformation, function, and/or structure.

Example 1

As shown in FIGS. 1-5 , this section describes a bicycle carriergenerally indicated at 10 in FIG. 1 . The carrier includes a fork mount12 to secure a front fork 14 of a bicycle 16, and a tail mount 18 tosecure a rear wheel 20 of the bicycle. The fork mount is coupled to afirst crossbar 22 on the roof of a vehicle 24, and the tail mount iscoupled to a second crossbar 26, where each crossbar has a long axisperpendicular to a longitudinal axis or a direction of travel of thevehicle.

Fork mount 12 and tail mount 18 are coupled at corresponding pointsalong the long axes of crossbars 22, 26. That is, a line between thefork mount and the tail mount may be perpendicular to crossbars 22, 26and parallel to the longitudinal axis of vehicle 24. A longitudinal axisof bicycle 16 may be parallel to the longitudinal axis of the vehicle,when the bicycle is secured to fork mount 12 and tail mount 18.

FIG. 2 shows a side view of bicycle 16 positioned for attachment tobicycle carrier 10. Since an outer rim and tire of rear wheel 20 of thebicycle is secured to a wheel tray 28 of tail mount 18, while front fork14 is secured directly to inserts 30 of fork mount 12, bicycle 16 may besecured at an angle relative to the vehicle roof.

Front fork 14 is aligned with inserts 30 of fork mount 12, and a rearfork 32 of the bicycle is aligned with wheel tray 28 of tail mount 18.Wheel tray 28 and inserts 30 define a mount spacing 34. A bike length 36is defined from front fork 14 to a point 38 on the outer rim of the rearwheel that is to be secured to wheel tray 28. As shown in FIG. 2 , point38 is immediately below rear fork 32. To be correctly aligned, bikelength 36 and mount spacing 34 may match.

However, distance from rear fork 32 to front fork 14 may vary betweenbicycles, and mount spacing 34 may be determined by a distance betweencrossbars 22, 26. On some vehicles, the distance between crossbars maybe fixed and not adjustable. Tail mount 18 may be adjustable in order toallow a variety of bikes to be secured to a vehicle with a particularcrossbar spacing, or to allow a bike with a particular distance betweenforks to be secured to vehicles with a variety of crossbar spacings.

In some examples, wheel tray 28 may be adjustable between a plurality oflongitudinal positions, as described further below. In the picturedexample, wheel tray 28 of tail mount 18 may pivot about an axis parallelto the long axis of crossbar 26. Tail mount 18 may therefore be ablesecure a point on the outer rim of the rear wheel not immediately belowrear fork 32. Bike length 36 may be thereby modified to match mountspacing 34, and rear fork 32 may not be aligned with wheel tray 28.

Alternatively, or in addition, one or both of fork mount 12 and tailmount 18 may be flipped to modify mount spacing 34. That is fork mount12 may be mounted on crossbar 22 facing an opposite direction along thelongitudinal axis of the vehicle, and tail mount 18 may be mounted oncrossbar 26 facing an opposite direction along the longitudinal axis. Ascompared to the configuration shown in FIG. 2 , flipping fork mount 12may decrease mount spacing 34 and flipping tail mount 18 may increasethe mount spacing.

FIG. 3 shows fork mount 12 on crossbar 22. In addition to inserts 30,the fork mount includes an upper half 40 and a lower half 42. Each halfincludes a clamping surface 44, and the lower half pivots relative tothe upper half about a bar 46. Fork mount 12 may be coupled to crossbar22 by clamping upper half 40 and lower half 42 about crossbar 22. Thelower half may pivot through a plurality of positions, and may bedescribed as having an open position and a closed position. The preciserelationship of lower half 42 and upper half 40 when in the openposition and the closed position may depend on a shape or size ofcrossbar 22.

In other examples, fork mount 12 may be unitary, lower half 42 may movealong a vertical axis instead of pivoting, or the fork mount may becoupled to crossbar 22 by any effective means. For example, fork mount12 may include a flexible strap extending around the crossbar, or may bebolted to the crossbar. For another example, fork mount 12 may include aside clamp such as is described in U.S. Patent Application PublicationNo. 2011/0139841 A1. Fork mount 18 may also comprise a portion of a trayrack that is coupled to first and second crossbars of a vehicle.

In the present example as shown in FIG. 3 , clamping surfaces 44 arecontoured to conform to crossbar 22, and to form a space between theclamping surface of upper half 40 and the clamping surface of lower half42 when the lower half is in a closed position. The space may besufficient to receive crossbar 22. The crossbar is shown in FIGS. 1-5with an aerodynamic shape, but fork mount 12 may be configured to clampto any type of crossbar including round, square, or ovoid.

One or both of clamping surfaces 44 may include a pad 48. The pad mayinclude a compressible material to aid in a clamping action of forkmount 12 on the crossbar, and may be textured or have a surface materialwith a high frictional coefficient to improve grip on the crossbar. Forexample, pad 48 may be made of rubber, or foam with a silicone covering.Improved grip of clamping surfaces 44 may be desirable in order toprevent fork mount 12 from sliding along the long axis of crossbar 22 ortwisting relative to the axis.

Fork mount 12 further includes a clamp actuator 50, and a cover 52. InFIG. 3 , cover 52 is shown in an open position, while in FIG. 4 thecover is shown in a closed position. In the present example, cover 52opens by pivoting about an axis parallel to crossbar 22 and is securedby a snap-fit feature. In other examples, the cover may pivot aboutalternative axes, may open by another mechanism, or may be entirelyremovable from fork mount 12. Any cover may be used, or the fork mountmay not include a cover.

Clamp actuator 50 includes a handle 54 screwed onto a T-bolt 56. Anaperture extends through upper half 40, sized to retain T-bolt 56 withhandle 54 above upper half 40 and a head of the T-bolt below upper half40. Once fork mount 12 has been positioned about crossbar 22, clampactuator 50 may be used to secure upper half 40 relative to lower half42. That is, handle 54 may be used to extend T-bolt 56 through lowerhalf 42 and rotate the T-bolt such that the head of the T-bolt isreceived by a feature on a bottom surface of the lower half. Once thebolt head is received by the feature, handle 54 may be rotated relativeto T-bolt 56 and screwed further onto the T-bolt to secure upper half 40and lower half 42 about crossbar 22.

Cover 52 includes an elongate aperture 58. In order to close cover 52,handle 54 may be rotated until a lateral extent of the handle is alignedwith aperture 58. When cover 52 is in a closed position, as shown inFIG. 4 , handle 54 may extend up through the cover, with aperture 58closely conforming to the handle. Cover 52 may thereby prevent rotationof handle 54, further securing fork mount 12 to crossbar 22 when in aclosed position.

As shown in FIG. 3 , upper half 40 of fork mount 12 includes a passage60 extending through the mount parallel to the long axis of crossbar 22.The passage is configured to receive inserts 30 in first and secondopposing ends. In the pictured example, passage 60 and inserts 30 arethreaded. The inserts may be manually screwed into upper half 40, asindicated by the arrows. In other examples, inserts 30 may also beremovably secured in passage 60 by fasteners or by any effective means.

Each insert 30 is annular, including a grip 62, an engaging portion 64,and a clamping portion 66 that has a lateral clamping surface 68. Theengaging portion is entirely received by passage 60, while grip 62 andclamping portion 66 remain proud of the surface of upper half 40.Lateral clamping surface 68 may be partially or entirely planar and maybe substantially perpendicular to passage 60. Grip 62 may be configuredfor manual manipulation by a user, to install and remove inserts 30 fromfork mount 12. In other examples, grip 62 may include one or moretooling recesses or may have a hex shape for installation by wrench orother tool. Inserts 30 may further include any features or mechanismsappropriate to engage passage 60, upper half 40, or a bicycle frontfork.

Fork mount 12 may include a set of pairs of matching inserts 30. A usermay select and install a pair of inserts appropriate for each bicycle tobe secured to fork mount 12. The user may switch pairs of inserts whenchanging bicycles, may leave one pair of inserts installed whenrepeatedly securing one bicycle, or may install or remove inserts asneeded or preferred. Each pair of inserts may correspond to a bicyclefront fork spacing standard, and a bicycle front wheel axle standard. Afront fork spacing standard may also be referred to as hub width. Abicycle front wheel axle standard may include through-axle diameters,hub axle sleeve diameters, quick-release skewer diameters, and/or anyrelevant dimensional standard. A table of illustrative currentlystandard dimensions for front fork spacing and axle diameters is below,dimensions listed in millimeters (mm).

Axle Diameter Fork Spacing Through-Axle 12 mm 100 mm 15 mm 100 mm 15 mm110 mm 15 mm 150 mm Quick-Release  9 mm 100 mm

A set of inserts may include all known standards and combinations ofstandards, or may be a targeted subset of known standards. For example,a mountain bike set may be provided with pairs of inserts correspondingto common fork spacing and axle standards for mountain bikes. A set ofinserts may include inserts configured to fit a specific make, model,and/or style of bicycle. Any dimension of an insert may be selected tocorrespond to a standard or to a dimension of a specific bicycle orgroup of bicycles.

In the current disclosure, a standard may include a dimension or set ofdimensions published by any organization having authority in the art ofbicycle design, a dimension or set of dimensions used by one or morebicycle manufactures in the design of bicycles, and/or any otherdimension or range of dimensions known to those skilled in the art ofbicycle design.

Each insert 30 has an inner diameter, that may be consistent through thelength of the insert. The inner diameter may match an axle diameter, ofa through axle and/or a quick-release axle. In some examples, insert 30may have a variable inner diameter with a portion of the insert, such asclamping portion 66, having an inner diameter that matches an axlestandard.

Each insert 30 may have an outer diameter that differs between grip 62,engaging portion 64, and clamping portion 66. Engaging portion 64 has anouter diameter appropriate to mate with passage 60, while grip 62 has adiameter sufficient to prevent the grip from being received by passage60. The grip may also have a diameter comfortable for manualmanipulation. Clamping portion 66 may have an outer diameter matching anadjustment knob 70 and a cam brace 72, shown in FIG. 4 .

FIG. 4 shows fork mount 12 securing front fork 14 of bicycle 16. In thepictured example, bicycle 16 has a dropout style front fork 14. A skewerwith a cam assembly 74 at a first end 76 and a threaded second end 78extends through inserts 30 and passage 60. The cam assembly includes acam lever 80 and brace 72.

Cam lever 80 may be movably fixed to the skewer, such that the lever maypivot about an axis perpendicular to the length of the skewer. The camlever may pivot between two positions, an open position 82 and a closedposition 84. In the open position cam lever 80 may be spaced from brace72, while in the closed position the cam lever may engage the brace.Brace 72 may be slidably mounted on the skewer, such that when cam lever80 engages the brace, the brace may in turn engage front fork 14 ofbicycle 16.

As shown in FIG. 4 , adjustment knob 70 is screwed onto threaded secondend 78 of the skewer, opposite cam assembly 74. A first dropout of frontfork 14 rests on the skewer between lateral clamping surface 68 of afirst insert 30 and brace 72, while a second dropout of front fork 14rests on the skewer between lateral clamping surface 68 of a secondinsert 30 and adjustment knob 70. Each of brace 72 and adjustment knob70 may also have a lateral clamping surface that is partially orentirely planar, and is parallel and corresponding to lateral clampingsurfaces 68.

Adjustment knob 70 may include a spring, such that a portion of the knobconfigured to abut front fork 14 may move a limited amount relative to aportion of the knob configured to engage second end 78 of the skewer.Such limited movement may allow a margin of error in tighteningadjustment knob 70. For example, if adjustment knob 70 has beentightened until front fork 14 is firmly held, cam lever 80 might requirea difficult level of force to operate, but instead adjustment knob 70may compress and allow cam lever 80 to be easily pivoted to closedposition 84.

As shown in FIG. 4 , brace 72 of cam assembly 74 has an elongate shapewith a slot 86 configured to mate with a catch 88 on an interior face ofcam lever 80. As cam lever 80 pivots about its axis, catch 88 may slidethrough slot 86 of brace 72 toward second end 78 of the skewer. Camassembly 74 may include a lock core housed in cam lever 80, configuredto rotate catch 88 about an axis perpendicular to the extent of the camlever when a key is turned.

Catch 88 includes an asymmetrical tab, configured such that when thecatch is rotated to a first orientation shown in FIG. 4 , the catch mayslide through slot 86, but when the catch is rotated roughly 90 degreesto a second orientation, the catch may be prevented from sliding throughslot 86. Cam lever 80 may be thereby allowed to pivot between openposition 82 and closed position 84 when catch 88 is in the firstorientation, but be prevented from pivoting between positions when catch88 is in the second orientation. By turning a key to rotate catch 88 auser may hold front fork 14 of bicycle 16 against inserts 30, andprevent unauthorized removal of the bicycle. Other locking mechanismsmay be included in cam assembly 74 or any component of fork mount 12. Insome examples, brace 72 may be circular or square and may not includelocking features. Both brace 72 and cam lever 80 may have any effectiveshape.

To secure a bicycle with a quick release front wheel, a user may graspcam assembly 74 and insert the skewer through a first insert 30, throughpassage 60, and out of a second insert 30. The user may then threadadjustment knob 70 onto the protruding end of the skewer. After removingthe front wheel of bicycle 16, including the quick release mechanism,the user may rest the dropouts of front fork 14 onto the skewer. Theuser may tighten adjustment knob 70 until the dropouts or tines of thefront fork are lightly held against lateral clamping surfaces 68 ofinserts 30. Cam lever 80 may then be pivoted from open position 82 toclosed position 84, pushing against brace 72 and securing the dropoutsor tines against clamping surfaces 68.

To secure a bicycle with a through-axle front fork, a user may removethe front wheel and the axle. The user may position the apertures of thetines of the front fork adjacent to inserts 30 and insert the axlethrough the aperture of a first tine, a first insert 30, passage 60, asecond insert 30, and into an aperture of the second tine. The user maythen secure the axle as normal, in other words secure the axle in thesame manner as if fork mount 12 were a wheel. In some examples, securingthe axle may include threading a first end of the axle into the apertureof the second tine and then operating a cam lever at a second end.

FIG. 5 shows rear wheel 20 of bicycle 16 secured by tail mount 18. Thetail mount includes a wheel clamp assembly 90 and a body 92 with a clampportion 94. The wheel clamp assembly is pivotably mounted to the body,which is secured to crossbar 26 by the clamp portion. In the picturedexample, wheel clamp assembly 90 is mounted proximate a rear end 96 ofbody 92. In other examples, the assembly may be mounted at any pointalong the body including at a center point or proximate a front end 98.

Clamp portion 94 extends down from body 92 and includes a first arm 100,a second arm 102, and a clamp actuator 104. Clamp actuator 104 isconfigured such that rotating a handle of the actuator draws second arm102 toward first arm 100 and thereby clamps crossbar 26 between the twoarms. Each arm, 100, 102 includes an inner surface contoured to conformto a side of crossbar 26. Either or both of the inner surfaces mayinclude a pad. The pad may include a compressible material to aid in aclamping action of fork mount 12 on the crossbar, and may be textured orhave a surface material with a high frictional coefficient to improvegrip on the crossbar. Improved grip of arms 100, 102 may be desirable inorder to prevent tail mount 18 from sliding along the long axis ofcrossbar 26 or twisting relative to the axis.

In other examples, tail mount 18 may be coupled to crossbar 22 by anyeffective means. For example, the tail mount may include a flexiblestrap extending around the crossbar, or may be bolted to the crossbar.For another example, tail mount 18 may comprise a portion of a tray rackthat is coupled to first and second crossbars of a vehicle.

Wheel clamp assembly 90 includes wheel tray 28 and two buckles 106 fixedon opposing sides of the wheel tray. A strap 108 extending through rearwheel 20 between the spokes of the wheel and engaging with buckles 106secures the rear wheel against wheel tray 28. Wheel clamp assembly 90may pivot about an axis parallel to the long axis of crossbar 26, suchthat rear wheel 20 may be held securely against wheel tray at pointsaround the rim of the wheel different from a lowest point of the wheel.

Strap 108 is releasably anchored in a first of buckles 106, passedthrough rear wheel 20 and inserted in the second of buckles 106. Aplurality of teeth 110 on strap 108 engage in a ratcheting manner withthe second buckle, securing rear wheel 20 with increasing tension asstrap 108 is drawn through the buckle. To release strap 108, a leverportion of the second buckle may be pivoted to disengage from teeth 110and allow the strap to be pulled from the buckle.

Example 2

As shown in FIGS. 6-11 , this section describes a fork mount generallyindicated at 210. Fork mount 210 includes a connector assembly 212 and ahead portion 214. The head portion is configured to selectively clamp toa first crossbar on a vehicle rooftop, where the crossbar has a longaxis oriented perpendicular to a longitudinal axis of the vehicle. Theconnector assembly is configured to secure a bicycle front fork to thehead portion.

Head portion 214 is comprised of an upper half 216 and a lower half 218,where the lower half is pivotable relative to the upper half. Upper half216 and lower half 218 may open similarly to clamp jaws and the crossbarmay be received between the upper and lower halves. Head portion 214 hasa first end 220 and a second end 222, defining a mount axis 224 that isgenerally perpendicular to the crossbar when fork mount 210 is clampedto the crossbar. Lower half 218 pivots about a bar 226 disposedproximate the first end, while the second end opens to receive thecrossbar.

As shown in FIG. 7 , upper half 216 includes a lower surface 228contoured to closely conform to an upper surface of the crossbar. One ormore pads 230 may be disposed on the lower surface, comprised of acompressible material that may also be suitable to improve grip of aclamping action on the crossbar or limit scoring and other damage to thecrossbar due to a clamping action. Lower half 218 includes an uppersurface 232 similarly contoured to closely conform to a lower surface ofthe crossbar.

Upper half 216 further includes two bar cradles 234, 236 with firstcradle 234 disposed at a position spaced vertically upward from secondcradle 236, as shown in FIG. 8 . Both bar cradles 234, 236 are disposedat first end 220 of head portion 214. Lower half 218 includescorresponding bar 226, disposed at first end 220 and shaped to beaccepted by either of the bar cradles. When the bar is received by a barcradle, lower half 218 is pivotable about the bar, relative to upperhalf 216. Bar 226 and cradles 234, 236 may be parallel to the crossbar,such that lower half 218 pivots in a plane perpendicular to thecrossbar.

A user of fork mount 210 may seat bar 226 in a chosen cradle, whenclamping the mount to a crossbar of a vehicle. The choice of bar cradlemay determine a spacing between lower surface 228 of upper half 216 andupper surface 232 of lower half 218, which is the space available toaccommodate the crossbar. When the bar is received in first bar cradle234, fork mount 210 may effectively grip a crossbar with a smallercross-sectional area or diameter. When the bar is received in second barcradle 236, fork mount 210 may accommodate a larger crossbar. Someexamples may include one or more additional bar cradles, to accommodatea greater range of crossbar diameters. In some examples, lower half 218may be pivotably fixed to upper half 216 in a single permanentconfiguration.

A clamp actuator 238 selectively secures upper half 216 and lower half218 in a clamped position on the crossbar. In the pictured example,clamp actuator 238 is comprised of a T-bolt 240 and a handle 242 screwedor otherwise coupled to a top end of the bolt. A passage 244 extendsvertically through upper half 216 of head portion 214, proximate secondend 222. A shaft 246 of T-bolt 240 extends through passage 244 and isretained in the passage by a combination of handle 242 at a top side ofpassage 244, and a head 248 of the T-bolt at a bottom side of thepassage.

An aperture 250 corresponding to passage 244 and sized to receive bolthead 248 extends through lower half 218. The aperture may have avertical extent through lower half 218, and a lateral extendcorresponding to a length of bolt head 248. The lateral extent ofaperture 250 may be aligned with mount axis 224.

To clamp the crossbar, handle 242 may be employed to urge T-bolt 240downward through aperture 250 and thereby move bolt head 248 clear oflower half 218. The handle may then be rotated, until bolt head 248 isaligned with a recess 252 in the lower surface of lower half 218 asshown in FIG. 9 . When the handle is released, the nut may be retainedby the recess, thereby maintaining the upper and lower halves in theclamped position.

In the pictured example, recess 252 is elongate and conforms closely tobolt head 248. A long axis of recess 252 is oriented generallyperpendicular to the lateral extent of aperture 250, and to mount axis224. In other examples, recess 252 may have any effective shape and maybe oriented at any angle relative to aperture 250. Lower half 218 mayalso include any features or fasteners appropriate to selectively engageT-bolt 240.

Once bolt head 248 is received in recess 252, T-bolt 240 may beprevented from rotating. The handle may then be rotated relative to thebolt and screwed further onto the bolt. The upper half may be therebyurged toward lower half 218, and the fork mount may be securely clampedonto the crossbar.

Referring again to FIG. 8 , the shaft of T-bolt 240 has a circularcross-section while passage 244 is elongate. That is, the passage doesnot conform closely to T-bolt 240 and instead is spaced from the boltalong a direction generally parallel to mount axis 224. Similarly,aperture 250 may be longer than bolt head 248. T-bolt 240 may thereforebe able to extend through upper half 216 and lower half 218 at a rangeof angles. That is, T-bolt 240 may form an angle with mount axis 224other than 90 degrees. FIG. 7 shows an example of such a configuration.

As lower half 218 pivots around bar 226, aperture 250 may be movedrelative to passage 244 along mount axis 224. T-bolt 240 may angle toaccommodate this relative movement and extend through aperture 250 whenthe aperture is not vertically aligned with passage 244. Bolt head 248may also be retained in recess 252 at a range of angles, due to thecorresponding rounded shapes of the nut and recess, shown in FIG. 9 .Therefore, lower half 218 may be clamped at a range of pivot positions,allowing fork mount 210 to clamp a range of crossbar sizes.

As shown in FIG. 7 , a cover 254 is mounted on upper half 216. The coveropens by pivoting about a bar 256 mounted in upper half 216, generallyperpendicular to mount axis 224. The cover may latch closed by means ofa snap-fit feature, or other fastener. Handle 242 has an elongate shapeand extends up through cover 254. The cover includes an aperture thatclosely conforms to handle 242, when the handle is aligned with mountaxis 224 as shown.

Referring again to FIG. 8 , handle 242 may be coupled to T-bolt 240 suchthat the length of the handle is generally perpendicular to the lengthof bolt head 248. As a consequence, handle 242 may only be admitted tothe aperture in cover 254 when bolt head 248 is aligned with recess 252of lower half 218. Effectively, cover 254 may only be closed when headportion 214 is clamped.

This may serve as a visual indicator of the mount's clamp status to auser of fork mount 210, and may help prevent the user from neglecting toclamp the mount before securing a bicycle to the mount. Handle 242 isalso prevented from rotating when cover 254 is closed. Cover 254 maytherefore serve to further secure head portion 214 to the crossbar, andprevent accidental disengagement of the clamp during transportation of abicycle.

In other examples head portion 214 may be monolithic, and may clamp tothe first crossbar by other mechanisms. Any appropriate clamp orselective attachment may be included in the head portion. For example,head portion 214 may be configured to attach to a specific geometry of aparticular crossbar design. For another example, head portion 214 may beconfigured to attach to an adaptor, that in turn engages a crossbar.

As shown in FIG. 8 , another passage 258 extends laterally through firstend 220 of upper half 216, in a direction parallel to the longitudinalaxis of the crossbar. In some examples passage 258 may extend throughlower half 218, or another part of head portion 214. The lateral passageis of sufficient size to accommodate connector assembly 212, whichcomprises a pair of selectable annular inserts 260 and aninterchangeable skewer 262 with a cam lever 264 and an adjustment knob266.

Each insert includes an outer engaging surface 268, a grip 270, and alateral clamping surface 272. Outer engaging surface 268 of each insertis configured to engage an interior surface 274 of passage 258.Different configurations of the outer engaging surface may be employedto secure inserts 260 to head portion 214. In the pictured example,outer engaging surface 268 and a portion of interior surface 274 arethreaded, such that the insert may be screwed into passage 258.

In an alternative example, outer engaging surface 268 and interiorsurface 274 may be shaped as complimentary cones. A projection may bedisposed on the outer engaging surface, and a channel of sufficient sizeto accommodate the projection may be recessed into interior surface 274.The channel may extend laterally along the interior surface for somedistance, and then deflect to one side at least sufficiently toaccommodate the projection in the deflected portion of the channel. Whenthe insert is installed, the projection may be aligned with the channeland the insert slid into passage 258, then the insert may be twisted tobring the projection into the deflected portion of the channel. Theinsert may be thereby retained in passage 258 and secured to headportion 214.

Grip 270 and lateral clamping surface 272 remain proud of head portion214 when the insert is fully secured in passage 258. The grip mayinclude a textured surface or be composed of a material appropriate toassist in the manual rotation of the grip. Grip 270 may facilitateinstallation of the inserts into head portion 214, and may remain proudof the surface of the head portion in order to facilitate removal.

Skewer 262 is of sufficient length to protrude through apertures in thetines of a bicycle front fork, passage 258, and inserts 260. The skewerhas two ends, a first threaded end 276 and a second end 278 with camlever 264. Adjustment knob 266 may be screwed onto the threaded end ofthe skewer once the skewer has been inserted through passage 258 andinserts 260.

FIG. 10 is a side view of connector assembly 212. Cam lever 264 has twopositions, clamped and unclamped, and is shown in the clamped position.The lever pivots around an axis perpendicular to skewer 262 defined by abar 280 that is coupled to the skewer. In addition, a brace 282configured to engage cam lever 264 is slidably mounted on skewer 262proximate the lever.

The distance between lateral clamping surfaces 272 defines a forkspacing 284 that may be a standard spacing from a set of fork spacingstandards for bicycle front forks. Fork spacing 284 may also correspondto a wheel hub width. The fork spacing may be determined by a spacingdimension 286 of each insert 260, from an outer edge of grip 270 toclamping surface 272. Each annular insert 260 also has an inner channelwith a diameter 288, shown in FIG. 11 . Inner diameter 288 correspondsto a standard for bicycle axle diameter. The inner diameter 288 may alsocorrespond to diameter 290 of interchangeable skewer 262 which in turnconforms to an axle size standard for bicycle front wheel axles.

A plurality of insert pairs may be provided as part of the bicyclecarrier, having a plurality of fork spacings and inner diameters. Anyappropriate combination of fork spacing and axle diameter may berepresented in the provided insert pairs. It should be noted that theinner diameters of any two pairs of inserts may differ, but the innerdiameters of the two inserts of a pair may match. If new standards forbicycle axle diameter or fork spacing are developed after a bicyclecarrier has been put into use, additional inserts or skewers thatconform to the new standards may be made available separately.

Prior to securing a bicycle to the fork mount, a user may select a pairof inserts 260 with dimensions appropriate to the particular bicyclebeing secured. Each pair of inserts may be configured to be secured inthe fork mount, and to accommodate an interchangeable skewer. Once apair of inserts 260 has been selected and secured in the fork mount, theuser may select a skewer 262 corresponding to the same axle standard asthe selected inserts. FIG. 11 shows four exemplary inserts A, B, C, D,each representing one of a pair of matching inserts. Inserts A, B, and Chave the same spacing dimension 286, but ascending inner diameters 288.By contrast, insert D has the same inner diameter as insert C, but has agreater spacing dimension. Therefore, inserts A, B, and would all beappropriate for bicycles made according to the same front fork spacingstandard, but according to differing axle standards. Differentinterchangeable skewers 262 would be appropriate for the three inserts.However, the same skewer may be used with inserts C and D.

In some examples, tines of a bicycle front fork may include featuresconfigured to engage lateral surfaces of wheel hub. Clamping surface 272of inserts 260 may be dimensioned or otherwise configured to engage sucha feature. For instance, tines of a bicycle front fork may include acircular recess disposed about the dropout and a diameter of clampingsurface 272 may correspond to a diameter of the lateral surface engagedon the wheel hub.

To secure bicycles with a drop-out style front forks, skewer 262 may beinserted through passage 258 and both inserts 260 of the fork mount withcam lever 264 in the open position. Adjustment knob 266 may be screwedonto threaded end 276 of the skewer until the knob and brace 282 areapproximately correctly spaced from inserts 260. The dropouts of thebicycle front fork may then be placed over skewer 262, and cam lever 264may be pivoted to clamped position. Adjustment knob 266 may be employedto further secure the tine and adjust the skewer while the cam leverremains in clamped position.

To secure bicycles with through-axle style front forks, skewer 262 maybe interchanged for the axle of the front fork. The fork tines may bepositioned abutting lateral clamping surfaces 272 of inserts 260, andthe axle may be inserted through inserts 260, and the tines. The axlemay be secured to the front fork according to the design of the bicycle.For instance, the axle may be threaded into a tine of the front fork, acam lever may be engaged, and/or any method used to secure the axle whenmounting a wheel to the front fork.

When either type of front fork is secured, a first tine of the frontfork is clamped between lateral clamping surface 272 of a first insert260 and brace 282, and the second tine of the front fork is clampedbetween lateral clamping surface 272 of the second insert and adjustmentknob 266.

Example 3

As shown in FIGS. 12-14 , this section describes a tail mount generallyindicated at 310. Tail mount 310 includes a tail portion 312 and a wheelclamp assembly 314. The tail portion is configured to selectively clampto a crossbar of a vehicle rooftop rack, where the crossbar has a longaxis oriented perpendicular to a longitudinal axis of the vehicle. Thewheel clamp assembly is configured to secure a bicycle rear wheel to thetail portion.

Any appropriate clamping mechanism may be used to clamp tail portion 312to the second crossbar. In the example shown in FIGS. 12-13 , tailportion 312 includes a body 316, a first arm 318, a second arm 320 and aclamp actuator 322 with a handle 324. First arm 318 is formed on body316, proximate one end and extending down from the body. Second arm 320is slidably coupled to body 316, extending down in a direction matchingfirst arm 318. The second arm is also operatively coupled to clampactuator 322, such that when handle 324 is rotated the actuator urgesthe second arm toward first arm 318, in order to clamp the crossbarbetween the first and second arms. First arm 318 and second arm 320 maybe contoured to conform closely to opposite sides of the crossbar.

As shown in FIG. 12 , wheel clamp assembly 314 includes a base 326, awheel tray 328, and a strap 330. A rear wheel of a bicycle may rest onwheel tray 328, and be secured in position by strap 330. A channel mayalso be formed in an upper surface 332 of the wheel tray, to aid incorrect positioning of the wheel. Base 326 is screwed or otherwisecoupled to a top portion of body 316, thereby securing the wheel to tailportion 312 and thus securing the wheel to the crossbar.

Strap 330 is received and secured by two buckles 334 on opposing sidesof wheel tray 328. In the pictured example, a first end of strap 330includes a bead 336 for retaining or anchoring the strap in one ofbuckles 334, against upward tension. The strap and buckle may alsoinclude releasable snap-fit features to retain the strap in the buckleagainst gravity or other forces.

In order to anchor the first end of strap 330, a second end of the strapmay be inserted from below, and up through the buckle until bead 336engages the buckle. The first end of strap 330 may be releasable fromthe buckle so that the strap may be anchored in the other of buckles334, to provide easy access on either side of a vehicle.

Once the first end of strap 330 is anchored in one of buckles 334, thesecond end of strap 330 may be passed through the spokes of thebicycle's rear wheel and then through the other of the buckles, to theextent necessary to secure the rear wheel of the bicycle to wheel tray328. Strap 330 includes teeth for ratcheting receipt in either buckle,to hold tension on the strap and keep the wheel secured.

A lever component 338 in each buckle may be actuated to release theteeth when adjusting strap 330 or removing the secured bicycle. Also,buckles 334 may pivot around an axis perpendicular to both wheel tray328 and the long axis of a clamped crossbar, allowing a greater range ofstrap orientation to secure wheels and tires of varying dimensions.

Strap 330 may be of any appropriate durable material, for exampleplastic or cut-resistant woven nylon fabric. In some examples, othertypes of adjustable buckle mechanism may be used, such as a ratchetstrap. Any effective mechanism may be used to secure the rear wheel towheel tray 328.

As shown in FIG. 13 , base 326 has an upper convex surface 340. Anelongated central aperture 342 extends longitudinally in the convexsurface, and wheel tray 328 includes a central aperture 344 laterallyaligned with aperture 342. A bolt, not pictured, may extend throughapertures 342 and 344 to secure wheel tray 328 to base 326 by engagingwith a top nut 346 and a bottom nut 348. Bottom nut 348 is disposed atan underside of elongated central aperture 342, and top nut 346 isdisposed at an upper end of wheel tray central aperture 344. A recess350 is formed in an upper surface 332 of wheel tray 328 and aboutcentral aperture 344, to receive top nut 346 such that the nut is flushwith upper surface 332.

Wheel tray 328 is configured to be secured at a plurality of positionsalong upper convex surface 340 of base 326. As shown in FIG. 14 , wheeltray 328 has a convex lower abutting surface 352 configured to rest onthe upper convex surface of the base. Central aperture 344 may belaterally aligned with elongated central aperture 342 at any point alongthe longitudinal extent of aperture 342, and the bolt securedaccordingly. Each position along upper convex surface 340 corresponds toa longitudinal position relative to the longitudinal axis of thevehicle.

Top nut 346 is a barrel nut with a generally circular cross-section,other than a recessed area to receive a head of the bolt. Recess 350 ofwheel tray 328 is rounded to conform to top nut 346, and allows the nutto be retained at any angle. Central aperture 344 is larger than theshaft of a bolt appropriate to mate with top nut 346 and bottom nut 348,and may be longitudinally spaced from the bolt. Therefore, the bolt mayextend through central aperture 344 at a range of angles. Together,these features may facilitate rotation of wheel tray 328 relative tobase 326, as measured around the long axis of the crossbar. Wheel tray328 may be pivoted through a range of angles, and may be secured at adesired angle when bolted to base 326.

A position and an angle for wheel tray 328 may be chosen to accommodatethe dimensions of the bicycle, so that the rear wheel of the bicyclerests securely on upper surface 332 of the wheel tray. FIG. 14 showswheel tray 328 in a first position 354 corresponding to a first positionand angle, and a second position 356 corresponding to another positionand another angle. Second position 354 may be appropriate for a longerbicycle than first position 354. Any appropriate combination of positionand angle may be selected by a user.

In some examples, wheel tray 328 may be permanently fixed to base 326 orto the tail portion. The wheel clamp assembly may be pivotably coupledto the tail portion, or may be coupled at a fixed angle. In the presentexample two nuts and a bolt secure the wheel tray to the base, but inother examples any effective arrangement of fasteners may be used. Wheeltray 328 is shown with a curved and elongated shape. In other examples,the tray may be planar or contoured, may be square, circular, or anyappropriate shape.
